The M109A4+ Self-Propelled Howitzer Memorial Monument and Gate Guard were made available through the Guns for Monuments Program offered by the Department of National Defence. The decommissioned and demilitarized Howitzer bears the number CFR# 68-34837, and serial number 2487. It was donated to the Municipality of North Grenville and the Veterans Way Memorial Committee by the Department of National Defence, and is dedicated to the memory of those that have served, and to those that continue to serve, the noble cause of Freedom and Democracy as members of the Canadian Armed Forces.
This Howitzer was part of a fleet of 76 guns that served with the 1st and 3rd Regiments of the Royal Canadian Horse Artillery, as well as with the 5e Régiment d'artillerie légère du Canada. The Howitzers were deployed at military bases in Canada and Germany from 1968, until they were declared surplus to the needs of the Canadian Armed Forces and withdrawn from service in 2005. The M109A4+ Self-Propelled Howitzer was placed in the park on July 16, 2015. The storyboard was added on September 27, 2015, during the Veterans Way Park dedication ceremony.
